EIGHT-DAY WATCH-MOVEMENT.

SPECIFICATION forming part of Letters Patent N 0. 453,952, dated June 9,1891.

Application filed July 19, 1890. Serial No. 356,307. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES GRANT WIL- soN, of New York, in the countyof New York, and in the State of New York, have invented certain new anduseful Improvements in Watches; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, in which-- Figure 1 is aperspective view of my movement from the rear side, the back plate beingremoved. Fig. 2 is a plan View of the same with said back plate inposition and the move- .ment contained within a case. Fig. 3 is a perspective of said movement from the front side, the dialand hours-handwheel being removed; and Fig. A is a plan view of the same with saidhours-hand wheel in place.

Letters of like name and kind refer to like parts in all of the figures.

The design of my invention is to render practicable the construction ofa watch-movement which shall be capable of running a week or more withone winding; and to such end my said invention consists in thecombination and arrangement of the parts of a movement, substantially asand'tt'or the purpose hereinafter specified.

In the carrying of my invention into practice I employ a front plate A,which is provided with four pillars a a a a, that are adapted to receivea sectional back plate B. A third plate or bridge C, having less heightthan said plate B, rests upon the plateA and is secured thereto bydowel-pins and screws in the usual manner.

Between the plates A and B is journaled an arbor d, that carries aspring-barrel D, while between said plate A and the bridge 0 arejournaled a second arbor c, carrying a pinion e and wheel E, a thirdarbor f, which carries a pinion f and wheel F, a fourth arbor g,carrying a pinion g and wheel G, and a fifth arbor h, carrying a pinionh and an escapewheel H, which arbors and their wheels and pinions arearranged in substantially the order An arbor 1T, journaled between theplate A and a cock K, and carrying a pallet-lever I, and an arbor Z,journaled between said plate and a cock M and carrying a balance-wheel Land hair-spring Z, completes the time-train, which is precisely the samelength as the ordinary thirty-hon r train and operates in the usualmanner.

The spring-barrel D has nearly twice the diameter that would be requiredfor a thirtyhour watch, and contains a spring which is materially longerand stronger than that usually employed, which construction enables thewatch to run for eight days with one winding.

Owing to the increase in the diameter of the barrel D, compared with athirty-hour barrel adapted for the train shown, a por tion of saidbarrel D overlaps the center of the movement. This renders it necessaryto change the location of the seconds-wheel, which, usually in theshort-time watches, is at the center of the watch, and accordingly itwill be seen that such wheel with its arbor and pinion are eccentricallylocated in my movement. Accommodation is thus secured for the enlargedbarrel without increasing at all the size of the watch as a whole.

The arbor 6 projects through the plate A into a recess a in the outerface of the latter, and upon its projecting end carries a toothed wheelN, which is held thereon by frictional contact and meshes with aseconds-wheel O, that is pivoted upon said plate. A centrallylocatedstud P projects forward from the plate A and carries a cannon-pinion Qof usual form, which pinion meshes with the" wheel 0, and is adapted toreceive and carry a minutes-hand upon the outer end of its sleeve orbarrel q. At one side of said wheel N and engaging therewith is atoothed wheel R, which has upon its upper side a pinion r, that mesheswith and drives an hours-hand wheel S, that is journaled upon the sleeveq of said minutes-hand wheel Q.

By the arrangement shown the minuteshand pinion Q receives its motionfrom the wheel N through the wheel 0, while the hourshand wheel Sreceives motion from said wheel N through the wheel R and its pinion 0-.

The arrangement of the time-train and dialtrain shown enables me toplace within the space usually given to the time-train of a thirty-hourswatch all that is requisite for securing eight days of time from onewinding of the spring and removes a serious objection to the use ofwatches of usual construction'viz., an occasional stoppage from afailure to wind the mainspring', such failure being far more liable tooccur where winding is required every day than where the spring is to bewound but once in a week.

Having thus described my invention, what I claim is 1. As an improvementinwatch-movements, in combination, a going-barrel adapted to run eightor approximately eight days after one winding, an escape-wheel, itsarbor and pinion, and three intermediate arbors, with their wheels andpiuions, the first of the latter arbors being, eccentrically located toaccommodate the going-barrel, substantially as and for the purposeshown.

2. As an improvement in watch-movements, a time-train which is composedof a main or first arbor, the wheel thereof, a second arbor journaledeccentrically with reference to the center of the movement-plates, thewheel and pinion thereof, and escapement, and the intermediate gearingbetween the latter and the wheel of the second arbor, said second arborbeing adapted to impart movement to the dial-train, substantially as andfor the purpose shown.

3. As animprovementin watch-movements, a time-train which is composed inpart of a main or first arbor, an escape-wheel arbor, and threeintermediate arbors, with their wheels and pinions, all of which are journaled eccentrically with reference to the center of themovement-plates, one of said intermediate arbors being adapted to impartmovement to the dial-train, substantially as specified.

4. As an improvementin watch-movements, a time-train which is composedin part of a main or first arbor, an escape-wheel arbor, and threeintermediate arbors, with their wheels and pinions, all of which are journaled around but not at the center of the movement-plates, and thehours and minutes hands are actuated through gearing that receivesmotion from the second arbor, substantially as and for the purpose setforth.

July, 1890.

5. As a means for driving the cannon-pim ion, which carries theminutes-hand, and in combination therewith, a wheel that is secured byfriction upon the second arbor, and a wheel which is placed between andmeshes with said wheel and pinion, substantially as and for the purposeshown and described.

0. As a means for driving the hours-hand wheel, and in combinationtherewith, a wheel which is secured by friction upon the second arbor,an intermediate wheel that meshes with and receives motion from saidsecond arborwheel, and a pinion which is secured to said intermediatewheel, and meshes with said hours-hand wheel, substantially as and forthe purpose specified.

'7. As an improvement in watches, in combination with the going-barreland the second arbor of a time-train, a pinion on the latter to drivethe same from said barrel, the wheel on the arbor, and the dial-trainreceiving motion from said wheel, substantially as and for the purposeshown.

8. As an improvement in watches, in combination with. suitablemovement-plates, a time-train and a stud at the center of the top platefor journaling' the hands and their sleeves, substantially as set forth.

9. In a watch, in combination, suitable movement-plates, a going-barrel,an arbor driven from the latter, and carrying a wheel on its upper end,journalcd eccentrically with reference to the movemen t-plates, a studat the center of the top plate, and the handscarrying wheels journaled011 said stud and driven from said first-mentioned wheel, substantiallyas and for the purpose shown and described.

In testimony that I claim the foregoing I have hereunto set my hand this8th day of CHARLES GRANT WILSON. Witnesses:
